Improved lubricator



UNITED STATES PATENT OEEICEo CHARLES SCHOTT, OF NASHVILLE, TENNESSEE.

IMPROVED LU BRICATOR.

Specication forming part of Letters Patent No. 57,196, dated August14,1866.

To all whom it may concern:

Be it known that I, CHARLES SCHOTT, ofthe city of Nashville, in thecounty of Davidson and State of Tennessee, have invented ce1- tainImprovements in Automatic Lubricators for Machinery; and I do herebydeclare that the followin g is a full, clear, and exact description ofthe same, reference being had to the accompanying drawings, making apart of this specification, in which- Figure l is a side view. Fig. 2 isa vertical sectional view, showing the internal construction of theapparatus.

The object of this invention is to obtain a lubricator for supplying oilto the journals of machinery, which will be automatically op erated bythe motion of the machine to which it is applied, which will furnish asteady and continuous supply of the lubricating material to the journalduring the operation ot' the machine, but stop such delivery whenthemachine is not in use, and Which will also possess the additionaladvantages of being adjustable in such a way as to regulate the quantityof oil furnished to the journal in proportion to the requirementsthereof, and of delivering only the clean oil, the sediment beingallowed to settle beyond the reach of the internal working parts of thedevice.

To enable those skilled in the art to understand the construction andoperation of my invention, I Will proceed to describe it with referenceto the drawings.

D represents the journal-box, and A the shaft or journal rotatingtherein. F is the cup which contains the oil. It is placed uponthe boxD, and incloses those parts of the apparatus which act directly upon theoil to feed it t0 the journal, these internal parts being operated, aswill be presently explained, by the movements ot' the lever B. Thislever is pivoted at s to the outside of the cup F, as shown in Fig. l,the pivot s passing through the cup and connecting the lever with theinternal mechanism.

Upon the opposite or extreme end of the lever B is a weight, G, whichcauses the said lever to fall and rest upon the stop z' when not incontact with the arm or cam I of the shaft A. This cam I may be made ofa strip of screw 'v holds these ends w to ether and' 7 7 7 also continesthereto the supplemental plate w, which thus forms a portion ofthe camI.

By making the plate fw longer or shorter the movement ofthe lever B willbe ,made greater or less, thus varying the movement ot' the internalmechanism and increasing or diminishing in proportion the amount of oilsupplied to thejournal.

It now remains to explain the construction of the parts contained in thecup F and clearly shown in Fig. 2.

a is a vertical tube, placed in the center of the cup F and passingthrough the bottom of the same. It is open at both ends, the lower endreaching to the shaft or journal A and the upper end extending upwardabove the surface of the oil. One side'or edge of this upper end is madehigher than the other, and is curved, as shown at n, in such a Way thatthe dippel's m, which elevate the oil, coming in contact with theinclined surface u, will deposit their adhering oil thereon. The dippersm are simply pendent pieces of Wire pivoted at one end to theratchet-wheel c, near the perimeter thereof, the said wheel being placedclose to the tube a at one side thereof. The ratchebwheel c receives a-nintermittent rotary motion from the pawl e, which is pivoted at o to thearm r, the said arm r being rigidly attached to the pivot s of the leverB. The lower edgeof the wheel c is immersed in the oil, through whichthe dippers m pass as the Wheel revolves.

The shaft or journal A heilig rotated as indicated by the arrow, the camI strikes against the under side of the lever B and elevates the same,thus moving the pawl c back over the teeth of the ratchet-Wheel c.A Thecontinued rotation of the cam 1v releasing the lever B, the said leverfalls until it strikes upon the stop i, its falling motion pushing thepawl e forward and partially rotating the wheel c. The dippers m arethus passed in succession through the oil, and when elevated above thesurface thereof the oil adhering to them collects upon their lower ends.The said lower ends strike against the curved surface n of the tube acarryingthe dippers, pawl 6,1ever B, and edm I, in relation to thejournal-box, in the mauner and for the purpose herein set forth.

CHARLES SCHOTT.
